Read my comment at the addon please and try to understand why there has not been any update since a few patches. It's about missing data and especially time needed to manually collect and update the data.
Prepare 1 single ressource with all the missing books, like an online google spreadsheet and maybe some dev with time and capacity left will be able to incorporate this into the addon then. But searching 100 comments about new books and checking the positions ingame for validity by the dev taking over the addon: I doubt this will happen and you should be able understand why
This is my answer without having checked if and what you have contributed so please do not think it was about you, it's a generic answer to all asking to update addons where there is a high manual effort to do for the authors and where the legwork should be done by the helping, and asking users, to make it smooth and easy to update the addons.
